Welcome to Eastsideboxing. Great question, Glass Jaws do absolutely exist in boxing, it's a proven fact although there are a crowd on this forum that still believe 'that punch would have ko'd anybody' despite all the evidence. Notable examples of fighters with Glass Jaws are: Amir Khan Roy Jones Jr Audley Harrison David Price Enzo Maccarinelli Hasim Rahman Jason Litzau There's more but this should get you started.
Wrong. Per capita. Usa has over 5 times the population of the UK so let's take USA's top 50 fighters from boxrec, compared to the UK's top 10. Find out how many times they have been knocked out collectively then work out the average per fighter: UK fighters have been KO'd 0.4 times USA 0.5 times Glass!!
Someone with a glass jaw is someone who cant take a Punch , are scared to take a Punch and sh*ts his Pants when he even thinks about getting hit , most Guys with so called glass jaws are simply Pus**s like Wladimir Klitschko , David Price, Amir Khan and Victor Ortiz . Someone with an Iron Chin is someone who does not give a sh*t about getting hit , he is willing to take a Punch and can handle it very good , These Guys are real Fighters with a fighters mentality like Dereck Chisora, David Lemieux , Evander Holyfield, Emile Griffith , Carl Froch and Antonio Margarito. Most of them are Pressure Fighters.
Price and Khan have two of the worst chins in boxing history. Khan has eaten the canvas vs someone with a 4% KO ratio....yes you read that right. Victor Ortiz is also glass jawed fighter, there is no debate on this. How many times has he been down now? He also suffers from a glass heart.
